  • the patent application JP 5-019543 A discloses a holding unit which is attachably/detachably mounted between the lower main body and the upper main body of a bisected type copying machine and near the turning fulcrum of the upper main body.
  • the unit is constituted of two cylinders whose either ends are closed, and a coil spring is housed inside the internal cylinder and always presses the internal cylinder upward. Pressing the cylinder upward is restrained by a stopper which can be engaged/disengaged.
  • An image recording apparatus 1 is a multi-function device (MFD) equipped with printing, copying, scanning, and facsimiling functions.
  • MFD multi-function device
  • an upper unit case 3 is perpendicularly swingably connected with hinges 4 to a side of a plastic lower unit case 2 of the image recording apparatus 1.
  • the lower unit case 2 has the following structure, which is not shown. That is, a recording portion using an inkjet method or the like is disposed above a sheet feeding cassette. A sheet of paper (recording medium) supplied from the sheet feeding cassette is transported to the recording portion through a U-shaped transport guide which is detachably attached to a rear side, a printed sheet is ejected from an opening which is formed above the sheet feeding cassette on a side of the lower unit case 2. The sheet feeding cassette is insertable through an opening.

  • the upper unit case 3 also includes a glass plate for supporting the original document, a document cover that covers the upper side of the original document, and an operation panel where a variety of operation buttons, a liquid crystal display and so forth are arranged (not shown).
  • the lower unit case 2 and the upper unit case 3 are respectively provided with a lower guide member 6 and an upper guide member 7, both of which extend from the hinge 4 side to an open end side.
  • An opening/closing linking unit 10 is disposed in connection with the lower guide member 6 and the upper guide member 7.
  • the opening/closing linking unit 10 is structured such that a first rotating member 12, which is movable along the upper guide member 7, and a second rotating member 13 which is movable along the lower guide member 6, are rotatably mounted on a spindle 14 (an example of a linking portion) fixed on a frame 11 having a certain shape.
  • the lower guide member 6 substantially horizontally and substantially linearly extends from the hinge 4 side toward the open end side.
  • the upper guide member 7 extends in a downwardly convex curve from the hinge 4 side toward the open end side (refer to Figs. 1A and 1B ).
  • the upper guide member 7 is disposed on the inner surface of the side plate of the upper unit case 3 such that a guide groove 23 is inwardly open (refer to Figs. 2A and 2B ).
  • the upper guide member 7 is positioned outside a lower guide member 6 of the lower unit case 2 in order to prevent interference of the intermediate portion of the downwardly convex upper guide member 7 with the lower unit case 2.
  • a circular-shaped braking member 15 which is a friction member having a large friction coefficient and formed of, for example, rubber, is fitted in a central portion in the axial direction of the spindle 14.
  • the braking member 15 is secured to the frame 11 or the spindle 14 with adhesive or the like so as not to rotate relative to the frame 11 or the spindle 14.
  • the first rotating member 12 and the second rotating member 13 are disposed on both sides of the frame 11 and the braking member 15 so as to sandwich the frame 11 and the braking member 15 therebetween.
  • the first rotating member 12 is disposed in such a manner that two large diameter rollers 12a and 12b (an example of two first large diameter rollers) sandwich a small diameter roller 12c (an example of a first small diameter roller) therebetween. These rollers are secured to each other with adhesive or the like so as to rotate as an integrated unit.
  • the second rotating member 13 is disposed in such a manner that two large diameter rollers 13a and 13b (an example of two second large diameter rollers) sandwich a small diameter roller 13c (an example of a second small diameter roller) therebetween. These rollers are secured to each other with adhesive or the like so as to rotate as an integrated unit.
  • the small diameter rollers 12c and 13c are formed of a material having a friction coefficient smaller than that of the large diameter rollers 12a, 12b, 13a, and 13b.
  • the lower guide member 6 is formed on the upper side of a side surface of the lower unit case 2.
  • the lower guide member 6 includes a guide groove 20, the vertical dimension of which is a little larger than the diameters of the two large diameter rollers 13a and 13b of the second rotating member 13, and ribs 21 and 22 (an example of a protrusion) that protrude so as to oppose each other from the top and bottom in the guide groove 20.
  • Upper guide surfaces 20a and lower guide surfaces 20b of the guide groove 20 face outer peripheries of the two large diameter rollers 13a and 13b.
  • the upper and lower ribs 21 and 22 face an outer periphery of the small diameter roller 13c.
  • the upper guide member 7 is formed on the inner surface of the side plate of the upper unit case 3.
  • the upper guide member 7 includes a guide groove 23 the vertical dimension of which is a little larger than the diameters of two large diameter rollers 12a and 12b of the first rotating member 12 and ribs 24 and 25 that protrude so as to oppose each other from the top and bottom in the guide groove 23.
  • Upper guide surfaces 23a and lower guide surfaces 23b of the guide groove 23 face outer peripheries of the two large diameter rollers 12a and 12b.
  • the upper and lower ribs 24 and 25 face an outer periphery of the small diameter roller 12c.
  • the first rotating member 12 and the second rotating member 13 are arranged such that the two large diameter rollers 12a and 12b (13a and 13b for the second rotating member 13) around the same axis (spindle 14) are spaced apart with the small diameter roller 12c (13c for the second rotating member 13) sandwiched therebetween.
  • the ribs 24 and 25 provided on the upper and lower guide surfaces 23a and 23b protrude so as to oppose the small diameter roller 12c
  • the ribs 21 and 22 provided on the upper and lower guide surfaces 20a and 20b protrude so as to oppose the small diameter roller 13c.
  • the upper unit case 3 is supported by the first rotating member 12 of the opening/closing linking unit 10, and the second rotating member 13 of the opening/closing linking unit 10 is movable along a lower guide surface of the guide groove 20 of the lower guide member 6 that is parallel with the x-axis. It is assumed that a position where the first rotating member 12 contacts an upper guide surface of the guide groove 16 of the upper guide member 7 (contact point) is away from the origin O by the distance d in the x-direction. In this case, it is assumed that the contact point P is positioned on the x-axis.
  • the contact point P is positioned on a side that is closer to the hinges 4 than the central axis of the first rotating member 12 is.
  • a load N that acts on the opening/closing linking unit 10 is caused by, for example, a frictional force and a brake force generated when the opening/closing linking unit 10 moves along the lower guide member 6 of the lower unit case 2, or a contact friction force generated between the first rotating member 12 and the side surface of the upper guide member 7 and between the second and third rotating members 13 and 14 and the side surface of the lower guide member 6, and a brake mechanism that stops the rotation of the first to third rotating members 12, 13, and 14.
  • the user pushes down on the upper unit case 3 with the load W in a closing operation. Therefore, as illustrated in Fig. 2B , upper peripheries of the large diameter rollers 12a and 12b of the first rotating member 12 are pressed against the upper guide surface 23a of the upper guide member 7. The lower peripheries of the large diameter rollers 13a a and 13b of the second rotating member 13 are pressed against the lower guide surface 20b of the lower guide member 6. Therefore, the first rotating member 12 and the second rotating member 13 rotate in opposite directions. For example, in a side view of Fig. 1A , when the closing operation causes the opening/closing linking unit 10 to move to the right, that is, away from the hinges 4, the first rotating member 12 rotates counterclockwise and the second rotating member 13 rotates clockwise.
  • the braking member 15 is disposed between the first rotating member 12 and the second rotating member 13, and the side surfaces of the braking member 15 are slidably contacted by side surfaces of the large diameter roller 12b of the first rotating member 12 and a side surface of the large diameter roller 13b of the second rotating member 13. Therefore, with frictional force here, the load N that is directed opposite (toward left) the moving direction of the opening/closing linking unit 10 is applied to the opening/closing linking unit 10.
  • V a * mg * cos ⁇ * U / b Since U and V are constants that are determined when the weight of the upper unit case 3 and the position of the first rotating member 12 are determined, the function S is a linear function of W.
  • the horizontal axis represents W and the vertical axis represents S.
  • the upper guide member 7 is formed so as to have a downwardly convex shape
  • the lower guide member 6 is formed so as to have a linear shape and horizontal orientation
  • the opening/closing linking unit 10 is movable therebetween.
  • the user applies an upward force to the free end or the like of the upper unit case 3 in opening the upper unit case 3.
  • This causes, as illustrated in Fig. 2A , the lower rib 25 of the upper guide member 7 to upwardly press against the outer periphery of the small diameter roller 12c.
  • a reaction force here causes the upper rib 21 of the lower guide member 6 of the lower unit case 2 to contact the outer periphery of the small diameter roller 13c.
  • the first rotating member 12 does not rotate but slips (slides) along the upper guide member 7 and the second rotating member 13 does not rotate but slips (slides) along the lower guide member 6.
  • the opening/closing linking unit 10 can move so as to approach the hinges 4. This achieves advantages of decreasing the force applied by the user in an opening direction and of making an opening operation of the upper unit case 3 easier.
  • the downward pressing force W by the user can be a constant force regardless of a width of an opening angle of the upper unit case 3.
  • the user applies an upward force at a position such as the free end of the upper unit case 3 so as to cause the opening/closing linking unit 10 to move closer to the hinges 4 along the lower guide member 6 and the upper guide member 7.
  • the movement of the opening/closing linking unit 10 stops at a position where the opening/closing linking unit 10 rests when the application of the force is stopped.
  • the opening angle of the upper unit case 3 can be maintained.
  • the opening/closing linking unit 10 is given a load toward the hinges 4 by using urging mechanism having the following structure. That is, the urging mechanism includes a tubular case 30, inside of which a fixing end of a spiral spring is secured, and a string 31 (an example of am urging member), which is formed of a flexible material such as a wire and a fixing end thereof is connected to a free end of the spiral spring. A force in a wind-up direction is applied to the spiral spring in advance and the urging mechanism is set to urge most of the string 31 to be wound up inside the case 30.
  • the case 30 is secured inside the lower unit case 2 on a side close to the hinges 4, and the free end of the string 31 is connected to the frame 11 of the opening/closing linking unit 10 (refer to Figs. 1A and 1B ).
  • the opening/closing linking unit 10 may be given an urging force (a load) toward the hinges 4 with the following structure. That is, a telescopic hydraulic or gas cylinder may be secured inside the lower unit case 2 and the top end of the piston rod may be connected to the frame 11.
  • the second embodiment which is not shown, is as follows. That is, the lower guide member 6 having an upwardly convex shape is disposed in the lower unit case 2 so as to extend from the hinge 4 side toward the open end side.
  • the same operational effect as achieved with the first embodiment can be achieved with the structure of the second embodiment.
  • the linearly shaped upper guide member 7 extending toward the open end side may be upwardly or downwardly inclined.
  • a recess (not shown) is provided at a position away from the hinges 4 in the lower guide surface of the lower guide member 6 (31 in the second embodiment) so as to cause the second rotating member 13 (36 in the second embodiment) to be fitted thereinto when the upper unit case 3 is closed with respect to the lower unit case 2.
  • This fitting of the second rotating member 13 (36 in the second embodiment) into the recess provides a clicking sensation at a closing end position of the upper unit case 3 and allows the upper unit case 3 to be fully closed.
  • first rotating member and the second rotating member are disposed to rotate coaxially.
  • the present invention according to claim 1 may be implemented in a variety of embodiments. That is, the upper and lower unit cases can be used as bodies and covers of electrical appliances, furniture, and fixtures as well as the image recording apparatuses.
